following:
• Set the start and stop frequency selection to the system
defaults (4 950 MHz to 5 825 MHz) by clicking
the Default button.
• Enter custom start frequency and stop frequency values for
the frequency band that must be scanned for interference,

• When the frequency scan is complete, the Spectrum Graph
window will show the scan result.
• Signal quality for each channel is shown as a function of
signal noise quantity (in decibel-milliwatts) at each
frequency. The higher the value shown on the graph, the
poorer the signal quality. A green display indicates high
signal quality. Yellow indicates falling quality. If the signal
display is red, there is excessive signal noise.
